Okay, so now I'm trying this on my Desktop computer, which has an internal SB Audigy2 ZS. I followed this guide, post #3,
http://www.hometheatershack.com/foru...html#post40694, to set everything up. Here is what I am getting for my soundcard calibration now:

I'm concerned about the noise toward the upper end of the graph... is that normal or am I doing something wrong?
I'm actually starting to wonder if maybe it is my cable that I bought to use with the SPL meter's Analog output. The tag on it says "1/8" mono miniplug to RCA phono plug". Is that the right one?
